You don't need to create keep grow prop up digitize worship and in general foolishly continue to put governments in power over you for this, or anything else. PGP WoT works entirely independent of and has no need for Government database bullshit. Create whatever keys for whatever nyms you aspire to, demonstrate and hold them out for others to sign to whatever degree they wish, hit send, and around the globe it goes. No Govt "authorities" DB's Bio-ID's etc needed.
even Werner Koch (Germany) the author of GnuPG does not use this system

for free
Nothing is ever free except charity, but you gave away that personal responsibility to Govt too, now they steal many times the amount from you, and fuck it up. And in this case, "free" is being used as a scam to lure people into permanent central Bio-ID dependency structures GovCorp digital slavery and control systems, lifetime tracking spyveillance and datamining, and worse... and you're falling for it. That's very bad and never ends well, ever. https://en.wikipedia.org/wiki/IBM_and_the_Holocaust
